We look at the division of 646178 by 29 
We're looking to find how many times 29 goes into 646178.

Advancing to step 1:
When dividing 6 by 29, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 29

Moving on to step 2:
The number 29 fits into 64 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 58 from 64 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 29

Step 3:
The number 29 fits into 66 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 58 from 66, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 29

Advancing to step 4:
When dividing 81 by 29, we get 2 with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 222.0
The remainder is 23 after subtracting 58 from 81.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 29

On to step 5:
If we divide 237 by 29, we get 8 and a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 2228.0
Subtracting 232 from 237 leaves us with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 29

On to step 6:
When dividing 58 by 29, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 22282.0
Subtract 58 from 58 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
The number 29 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22282.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
29 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22282.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 22282.0 and a remainder of 0.0.
